11. What are some of the distinguishing properties of the class of proteins referred to as GTPases? How are these proteins regulated? Describe the typical cycle of how GTPases typically interact with and/or regulate their partner proteins, and any important classes of proteins that regulate the state or function of GTPases. Choose a specific GTPase protein that we have discussed so far this semester and, briefly, describe its function.
